**SUPPLEMENTARY INFORMATION:**
This document describes a strategy for developing the Causal Analysis/Diagnosis Decision Information System (CADDIS). CADDIS is envisioned as a decision support system that will help investigators in EPA Regions, states, and tribes find, access, organize, and share information useful for causal evaluations in aquatic systems. It will include supporting case studies and analysis tools, and it will provide access to databases that contain information useful for causal evaluations. The system will be developed incrementally and iteratively, and frequent user input and feedback will be essential to the system's success.
